Ogawa Technical Works Co., Ltd. manufactures metal products and parts for cutting-edge fields such as aircraft, semiconductors, and medical, as well as architecture and all other fields.

Our strength lies in our comprehensive ability to flexibly combine processes that make full use of a variety of manufacturing methods, from manufacturing using state-of-the-art equipment such as 5-axis processing machines to handwork (welding, polishing, assembly, etc.) that only skilled craftsmen can perform.
In addition to manufacturing, we can also assist with upstream processes such as design and development support using 3D CAD.

Customers who are looking for a new supplier and customers who have no knowledge of manufacturing are also welcome.
If we can be of any assistance to you, please feel free to contact us.

Frame structure, Welding, Polishing, Assembly


We handle processing processes that can only be done by hand, such as buffing, welding, and assembly.
We also specialize in the production of frames, frames, and trolleys using can manufacturing, as well as general-purpose sheet metal processing.

Skilled workers are retiring one after another, and there is now a serious shortage of workers in this type of handwork, but we are working to pass on this handwork craftsmanship to young people as soon as possible, and have established a system that will allow us to continue supplying this work for the next 30 years. Ta.

Please leave the manufacturing, welding, and polishing of medical equipment, food machinery, and physical and chemical equipment to us.

Precision parts


We manufacture parts for cutting-edge fields such as semiconductor manufacturing equipment, aircraft, medical and physical science, and industrial machinery.

Through collaboration with over 100 partner companies in Japan, we are able to undertake any manufacturing process.

We have a lot of experience in machining complex shapes using advanced machine tools such as 5-axis processing machines, and in complex process parts by combining various machining processes.

Engineering support


We will assist you with the overall design and development of new equipment, automated machinery, and jigs.

Since it is possible to design using 3D CAD, you can proceed with development while checking that we are meeting your needs at any time.

In addition, if you have the actual item but no drawings, we also accept "reverse engineering", which converts the actual item into 3D data and creates manufacturing-ready drawings.
